Juncker also blamed Germany for treating the eurozone “as its subsidiary” and taking eurozone decisions according to internal political interests. “If all 17 governments would do this, what would be left of that was is common? Why is it like this?” he said.

He criticised German politicians – including German economy minister Phillipp Roesler – who in recent weeks have said a Greek exit from the eurozone would be better than keeping the country in.

“Those who think a Greek exit would solve the problem are wrong. They do not understand a thing about the deep origins of the crisis. Greece needs to improve its record, certainly. But nobody can ignore the staggering cost of an exclusion for the others. Anything else is low politics,” Juncker said.

Meanwhile, over 71 percent of Germans want Greece to leave the euro if it did not live up to its austerity promises, a poll published Sunday by Bild newspaper shows.

Over 50 percent of Germans also think their country would be better off outside the euro. Only 29 percent said the German economy would hurt if it was to leave the common currency.
